RAIL-JOINT.

Specification ofvIetters Patent.

Application med August 11, 1906.- fserisl No. 330,255.'

To *allwhiom it may concern:

Be it known that I, BANcRor'r GJBRArNna citizen of thejUnitedS-tates,residing at New York city, inthe and has special reference to animproved principle of construction applicable to various types of railjoints 1 and providing what may be vcharacterized as a binding 'meansfor interposed or inserted surface-plates suchv as insulationplatesemployed in insulated rail joints, or bonding plates such asemployed in conjunction with rail joints fitted or equipped with arailbondng means.

lTo this end the invention primarily contemplates a novel and eiectivebinding means for insulation or bonding plates which provides for firmlyand tightly securing such plates in intimate contact with the opposingbear-ing surfaces of the rail and the rail joint Also, this phase of theinvention involves a construction which not only has the function ofbinding or fastening an insulation or bonding plate in its properapplied position, but which Valso possesses specialutility as apractical structural erpedient fo'r tightly wedging an insulation plateor sheet permanently in its proper'position and effectually prev ventinginsulating material from flowing under load 'strains or otherwiseworking out of .position as is the vcase at times with some types oiinsulated rail joints.

In carrying out the invention, aside from the 'genL eral applicationthereoi as a binding or fastening means .for interposed or insertedplates of'any character, the

same provid'esa construction which is specially' applicable. asanimprovement to that standardized type of insulated rail joints 'nowknown to railway engineers -as 'the continuous insulatedjoint vandwhichis exemplified by the former patents to the applicant, viz:v

# 731,016, dated June 16,1903 and 779,066, dated January 3, 1905, andalso by the patent, to'Fearey',

1# 582,907, dated May 1S, 1897v and alsouby Patents Nos. 782,645 and 797 ,490.,` Although of practical utility inconnection with this specialtype oi finsulatedjrail joint, 'the inventionis necessarily applicable'to any type of joint` wherein it'is desirable to secure the resultscontemplated by the'oregoing objects.- A

With these and many `other objects in .view which will readily-appear tothose familiar with the art as the ,I nature of. the invention is betterunderstood, the same consists in the novelconstruction, combination, and

arrangement of parts hereinafter' more fully described,

' illustrated, and` claimed. A

The essential features of the invention involved in the relation o theangles ofthe opposingbearingfaces of the rail and the rail joint membersor plates, isnecz a,timmtlie'rails AfA and the opposite l continuous`side essarily susceptible to a wide range of plates, y'whether in shortsections or flcation and also to a wide range 1of application to variouttypes of joints, and various combinations. without departing irom thescope of the invention, certain preferred embodiments o'f which aresuggestedV in the accompanying drawings, in which:

Figure l is a sectional perspective view of a rail joint 'of thecontinuous type embodying binding means contemplated by the presentinventiom Fig. "2 is an enlarged cross sectional view ofthe same type ofjoint, showing one of the side angle plates drawn tight against side ofthe, joint shown with theiparts slightly separated and illustrating howthe surface plate may-be of 654 the interposed or inserted surface plateand opposite' substantially uniform thickness instead of correspondingin taper to the wedging or tapering spaces between Fig. 3 is a crosssectional 'view similar to Fig.- 2 showing the opposing faces of therail and the rail joint member.'

the provision of a positive gripping surface on the bearing face of oneor more of the bearing faces ofthe'rail joint members for moreeffec'tuallyl pinning ber or bond in position. Fig. -4 is a crosssectional view showing the lapplication 'of the 'improvement to theplain. angle bar type of rail joint.

Like references designate corresponding parts in the several gures ofthe drawings. l j

In carryingout the present invention, no change is required in thegeneral organization of the parts of anytype or' rail joint to `.whichthe' saniemaff be applied, nor any radical departure necessitated in thestructural features oi such jointpas the improved'feature oiconstruction which provides a deniteand positive bind# ing means forinterposed or inserted plates such-as insulation plates or bondingplates is necessarily'applicable to any type oi rail joint utilizingsurface plate of this general character. Furthermore, the binding orpinning means provided by the present invention may be utilized in avariety of .ways and in dierent positions or locations as a-fasteningfor insulation plates or bonding whether detachable orpermanentlypositioned. lilVhile susceptible to this widerange ofapplication and t'uncfull length, and .I

tion, the invention, however, possesses special utility as abinding orpinning. means for insulation .plates and-is hence of special and.practicalvalue in connection with insulated rail joints. In this phase,the invention also provides certain novel and improvedfunctions in con@y nection with that type of insulated rail joints characterf ized byrailway engineers as the continuous rail joints and exemplielrorinstance, in the applicafitsformer patents,hereinloeore referred to, sofor. illustrative purposes, the preferred embodiments of .the inventionare shown in Figsyl', 2, and 3 of theidrawings. Inthese figures therailjoint illustrated is of the continuous type referredto andessentially includes in its general organi- A y ing face 3 opposing thecorresponding inclined bearing face 4 at, the under side of the railhead 5. Also, each v of said continuous side plates 1 is formed at thelower edge of its vertical member with aninclining foot flange 6 lyingover the rail base and provided at its under side with an inclinedbearing face 7 opposing the corresponding bearing face 8 on the upperside oi the base liange 9 of the rail. 1n addition to these features,each continu- 'ous side plate l. of the type of joint referred to hasextended from and below the outer edge oi its foot {lange- 6 a baseflange extension 10 occupying a substantially horizontal position andlyinor beneath the base flange oi' .the rail. The said base flange 10 ofthe side plate is provided at its upper side with a bearing face 1lopposing the corresponding bottom i'ace l2 of the rail. ln the insulatedcon tinuous rail joint of the type herein described, an insulation plateor sheet13 is interposed between the opposing faces of the rails and theside angle plates 1. These insulation plates or sheets 13 are usually-ofa continuous form and not only face the sides of the rail joint, but arealso formed with top flanges 14 lying between the upper bearing faces 3ofthe side plate and the under bearing face 4 of the rail head and withfoot-pieces between faces 7 and 8. Also, the insulated plate or sheet 13is provided with a base piece 16 lying between the bearing faces 11 and12.

vA distinguishing feature of the present invention re- Isides in theexpedient of making one or more of the an gies of the bearing faces ofthe rail joint plate oi" a greater degree than the angles `ofthe-corresponding bearing faces of the'rail, thus forming a binding orfastening wedge which serves to securely Vpin the interposed or insertedplates in a fixed position -and prevents the same from creeping orworking out of place as is sometimes the case in connection withinsulation plates. In

this particular function it should be noted at this point that the topflange 14 of the insiilation plate 13 sometimes has a tendency to workoutward'between the opposing bearing surfaces 3 and 4, whereas,according'to the present invention, the wedging action of the bearingface 3 positively prevents this result and therefore retains a moreperfect and desirable insulation of the joint. I A

The result referred to is accomplished by having the angles of thebearing faces of the rail joint members different ironi the angles ofthe corresponding rail faces, although it will be observed from thedrawingsthat in the preferable construction they angles of the bearingfaces 3, 7 and 11 are greater than-the rail faces opposing the same andare disposed in directionsto secure a similar wedging action upon themembers 14, 15, and 16 of the insulation when the side or joint platesare tightened up.

Of course, the wedging feature on the joint plate may be applied to oneor more points according to the type resaca have the pinned portions ofthe surface plate 13 of a tapering thickness, yet the invention may becarried.

out by having such portions of the saine thickness as suggested in Fig.2. Again, if desired to secure a more effective pinning action, one ormore of the bearing faces of the joint plate may be concaved asindicated at i7 in Fig. 3 ot the drawings, to provide a-positivegripping snrface upon said bearing.

To illustrate the range of applicability to different types of joints,there is shown in Fig. 4 of the drawings a plain angle bar type ofinsulated rail joint including in its construction the side'angle bars18 having the upper and Alower bearing faces 19 disposed at a greaterangl e than the corresponding bearing faces 20 of the rail R andcooperating withv the flange portions 21 of the inf sulation plate orsheet 22 in the saine manner as herein' described. i

I claim:

1. In a rail joint, the rails. opposite separated horizon-=tallymovalile independent joint members, each having a hearing facedisposed at a greater angle than the corresponding rail face, and aplate element pinned between said opposing faces.

2. In a rail joint, the rail having a plurality of bearing faces, and arail joint member likewise havinga plurality of bearing faces disposedat a different angle from those of the rail, and plate elementspinnedhetween said faces.
